KLA (NASDAQ:KLAC) stock has now logged five straight sessions of gains, climbing a total of 11% over that stretch. The company provides process control and yield management solutions for semiconductor industries, including defect inspection, metrology (the science of measurement), process monitoring, computational lithography, and data analytics products.
The rally has been fueled by growing expectations of a Federal Reserve rate cut this month, which has lifted sentiment across tech and semiconductor stocks. Adding to the momentum, renewed AI enthusiasm – highlighted by high-profile deals and Oracle’s blockbuster AI cloud compute guidance – has further boosted the sector.
